ELECTRO-HARMONIX VINTAGE PEDALBOARD

This Pedal Board is composed of mostly-Vintage Electro-Harmonix Pedals from the late 70's. The Board is constructed with 10mm Plywood covered with Black Ozite Carpet and a Voodoo Lab ISO 5 Power Supply keeps the pedals powered and keeps the noise out of the audio. The pedals are set into routed spaces on the top of the board which keeps them from moving around and a big-black-bungee cord keeds them down... whoa mama.

Old-School, molded-end 1/4" jumpers are period correct and are used to connect the pedals together. All of the cables are hidden/ protected by a plastic cover that is easily removeable for access.

The Soul Preacher Compressor is first in the chain, then there is a true bypass switcher to switch four of the other FX in & out. The four FX that are switched are the Octave Multiplexer, the Zipper Envelope Follower, Bad Stone Phase Shifter and Electric Mistress Flanger. The Switcher has an INSERT JACK that allows a Big Muff Pi Fuzz to be inserted between the Zipper Envelope Follower and the Bad Stone Phaser... that way the Bad Stone Phase Shifter and Electric Mistress Flanger come after the Big Muff. The last effect is a Current Production Holy Grail Reverb pedal.

Loops #1, #2, and #3 of the Bypass Switcher are composed of 3PDT switches that allow True-Bypass switching and LED indication of when the FX are ON. Switchcraft #11 1/4" Jacks are used on all of the Bypass Switchers IN's and OUT's. The Electric Mistress created a really bad "pop" in the audio when switched in/out so, Loop #4 in the Bypass Switcher was retrofitted with a Jack DeVille -  Click-Less™ True-Bypass Kit and everything is silent now.

This conglomeration of old-school pedals plays nice at the front of any amp and is fun to play with these revered Electro- Harmonix pedals.
